About BSC
The Barcelona Supercomputing Center - Centro Nacional de Supercomputación (BSC-CNS) is the leading supercomputing center in Spain. It houses MareNostrum, one of the most powerful supercomputers in Europe, was a founding and hosting member of the former European HPC infrastructure PRACE (Partnership for Advanced Computing in Europe), and is now hosting entity for EuroHPC JU, the Joint Undertaking that leads large-scale investments and HPC provision in Europe. The mission of BSC is to research, develop and manage information technologies in order to facilitate scientific progress. BSC combines HPC service provision and R&D into both computer and computational science (life, earth and engineering sciences) under one roof, and currently has over 1000 staff from 60 countries.

Context And Mission
We are looking for software atmospheric modeler to join the Atmospheric Composition group within the Earth Sciences department at the BSC-CNS. Composed of about 50 members (research engineers, predocs, postdocs, senior scientists), the AC group aims at better understanding and predicting the spatiotemporal variations of atmospheric pollutants along with their effects upon air quality, weather and climate (see a video presentation of the group in). This is addressed through the continuous development and application of numerical models over multiple scales, from weather to climate and from global to urban scales. The AC group is the research backbone of the Multiscale Online Non-hydrostatic AtmospheRe CHemistry model (MONARCH), a cutting-edge atmospheric composition model used for both research and operational activities, that contains advanced chemistry and aerosol packages coupled online with a meteorological driver. MONARCH is part of the ensemble Copernicus Atmospheric Monitoring Service (CAMS) regional air quality forecasting system that provides operational forecast and analysis over Europe. CAMS is a key component of the European Union’s Earth observation system. MONARCH also runs operationally at the first World Meteorological Organization (WMO) Barcelona Dust Regional Center (BDRC) for Northern Africa, the Middle East and Europe, and the International Cooperative for Aerosol Prediction (ICAP) ensemble of global aerosol forecasts.
Exploitation of novel high-resolution emission inventories requires going toward higher spatial resolution to prepare the next generation of air quality predictions in Europe. We are seeking a highly motivated Research Engineer or Postdoctoral Researcher to join our team in the development of a physically consistent super-resolution downscaling deep learning models for chemical transport models (CTMs), able to predict high-resolution atmospheric composition fields (1-3 km) from coarse regional simulations (10-20 km). He/she will explore, adapt and improve cutting-edge deep learning architectures proposed in the field of computer vision and weather/climate sciences, including image- and video-based convolutional neural networks. Different strategies will be investigated to improve the physical consistency of the predicted high-resolution concentration fields, using soft and/or hard constraints. More sophisticated types of machine learning including for instance graph neural networks will also be explored. This research will start focusing on the Iberian Peninsula but should then scale to European scale (and in the future, to global scale).
The successful applicant will be part of an active group of researchers focusing on leveraging deep learning technologies to address key scientific and policy-oriented challenges (currently about 7 people in the AC group, about 15-20 in the BSC Earth Sciences department). To conduct this research, he/she will have access to the groundbreaking High-Performance Computing infrastructure of BSC, notably MareNostrum 5, one of the most powerful supercomputers in Europe, with a peak performance of 314 Pflops, 200 PB of storage and 400 PB of active archive, and an accelerate partition including 1120 nodes composed of 4 NVIDIA GPUs nodes. The candidate will also benefit from the collaboration with the Computational Earth Sciences group of the department, composed of experts in HPC, software development, and AI.
This activity is part of a large initiative on the “Modernization of observation networks and digitalization of production processes for the development of intelligent meteorological services in the context of climate change” in the framework of the European Recovery, Transformation, and Resilience Plan funded by the European Union-Next Generation EU.
Key Duties
Develop and implement deep learning architectures (e.g., CNNs, GANs, diffusion models) for spatial super-resolution of atmospheric composition fields generated by atmospheric chemistry models
